Hypericum beanii, commonly known as St John’s Wort, is native to central south China. In its native habitat it grows in open woodlands and thickets.

The etymological root of the binomial name Hypericum is derived from the Greek meaning ‘above pictures’, in reference to this plants use over shrines to repel evil spirits. Beanii is named after William Jackson Bean (1863 -1947), a British botanist and former curator of Kew Gardens.
